Hey folks,

This has been bugging me for a few days.  Keep getting the following error, but only after adding my newest rx480 GPU.

Tried with both 5.1 and 5.3

01:40:06:662 ccc GPU 2, OpenCL error -36 - cannot write buffer for DAG

I have all of the environmental variables set at the beginning of my batch file as shown below.
GPU_FORCE_64BIT_PTR 0
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100

I have 4GB physical memory
I have 16GB virtual memory set with 24GB max.  Windows 7 x64.

Hard drive is an older 7200rpm 250GB drive I had laying around.  Seems to work fine, no errors found when running disk check.

GPUS
290x - 4GB
380x - 4GB
390x - 8GB
rx480 - 8GB

GPU2 is the rx480.  I have no problems running the miner with the rx480 disabled.  I have tried both the newest 16.7.3 drivers as well as a clean install with the 16.7.2 drivers.  All 4 GPU's show up in device manager with no warnings.

Minor Detects GPU's as below.  (I notice the rx480 does not have a name next to it, not sure if this is of significance.)

Thanks in advance for any assistance!
